In Reply to: RE: Jim, what bias setting did you use to achieve 10,000 umhos with posted by Jim McShane on May 03, 2010 at 15:04:04
You mention using the exact chart settings for testing the EH7591, but in a previous post, you mentioned this:

Honestly, I think I just got mixed up or something - it looks like I was describing the EH KT-88 in the prior post!
Sorry, my bad!
....OUCH!
6L6 tube on my calibrated TV-7, and it tested right on the money. The 6L6 was sold to me by Sonny at the Radiola Guy, and it has a value of 42 units on the TV-7.
I re-tested my new EH7591, and I have a correction to make also. They measured 45 units on the TV-7. When I raised the bias to 23(the setting for the 6L6 tube), the EH7591 tested at 32 units. I guess that makes sense actually. So, I am not sure what to do to make the EH7591 measure like a normal, new 7591 tube.
